二头肌阵列是一项宇宙微波背景(CMB)偏振实验，将于2019年初开始在南极进行观测。这个实验用四个更大的BICEP3型接收器取代了组成Keck阵列的五个Bicep2型接收器，这些接收器在30到270 GHz的六个频率上进行观测。95 GHz和150 GHz的接收器将继续推进已经很深的Bicep/Keck CMB图，而30/40 GHz和220/270 GHz的接收器将分别限制同步加速器和银河尘埃的前景。在这里，我们报告了Bicep阵列仪器的设计和性能，重点是安装和低温恒温器系统。
Bicep Array is a cosmic microwave background (CMB) polarization experiment that will begin observing at the South Pole in early 2019. This experiment replaces the five Bicep2 style receivers that compose the Keck Array with four larger Bicep3 style receivers observing at six frequencies from 30 to 270GHz. The 95GHz and 150GHz receivers will continue to push the already deep Bicep/Keck CMB maps while the 30/40GHz and 220/270GHz receivers will constrain the synchrotron and galactic dust foregrounds respectively. Here we report on the design and performance of the Bicep Array instruments focusing on the mount and cryostat systems.
